Use Ice Packs Or Cold Cloths:
It is important to use cold compresses in order to soothe the irritated skin using face cloths soaked in ice-cold water or ice wrapped in a cloth greatly reduces the irritation and pain happening due to the heat rash. Try to apply some ice pack wrapped in a towel on the rash to soothe the skin and make your cold compress at home. In this way, you are bringing down the body temperature, which keeps the sweat production at bay.
